I received this email today....
John Walsh, who is on TV and whose son was abducted and killed, has started a
web site
www.familywatchdog.us
You put your address in and it will show you a map with your house indicated.
The people who have been arrested and convicted of sexual offenses will be
indicated by different colored squares, depending on their offense. You can
click on the squares and a picture of the offender, with other information will
come up.
